BACKGROUND OF THE INVENTION
This application is a continuation-in-part of copending application Ser. No. 09/606,694, filed Jun. 30, 2000.
1. Field of the Invention
The present invention relates generally to a mitt worn on a hand for use in cleaning, and in particular to a mitt for cleaning that is formed from a fabric that is electrostatically charged or can acquire a triboelectric charge upon rubbing a surface, or from a fabric that is rendered tacky by the application of a tackifying agent. The mitt has a compartment for a thumb on either side of a central axis of the mitt, allowing the mitt to be used on either hand. The present invention also relates to a method of producing such a mitt.
2. Description of the Related Art
Mitts for dusting and cleaning have typically had several disadvantages. A common problem with prior mitts that incorporate a defined thumb compartment is the inability to use both sides of the mitt for cleaning without removing the mitt from one hand and placing it on the opposite hand. This is inconvenient because users typically prefer to place the mitt on their dominant hand for cleaning, so it is awkward to move the mitt to the other hand to allow use of both cleaning surfaces of the mitt. Typically, those mitts that were able to be used on either hand and were also capable of having both surfaces of the mitt used for cleaning had no separate thumb compartment, which led to difficulty in controlling the mitts. Upon wiping such a mitt across a surface, there is a tendency for the mitt to rotate around the hand, or slip off altogether. Another problem with prior dusting and cleaning mitts is the lack of their efficiency in picking up and retaining dirt, which was frequently only shifted from one place to another.
- SUMMARY OF THE INVENTION
Accordingly, there is a need in the art for a cleaning mitt that can be used on either hand, and allows both cleaning surfaces to be used on the same hand. Such a mitt should provide separate compartments for the thumb, in order to provide greater control during cleaning. Further, the mitt should be made of a material that attracts and traps dust and dirt to prevent it from being scattered.
The present invention addresses the foregoing needs in the art by providing a mitt for dusting and cleaning, and a method of forming such a mitt.
In a first aspect of the present invention, a mitt for cleaning comprises an opening for inserting a hand therein, a section for the palm of the hand, a section for fingers, and a compartment for a thumb on either side of a central axis of the mitt, wherein the mitt may be used on either hand.
In another aspect, the present invention includes a method of forming a mitt for cleaning, comprising forming an opening for inserting a hand therein, forming a section for the palm of the hand, forming a section for fingers, and forming a compartment for a thumb on either side of a central axis of the mitt, such that the mitt may be used on either hand. Preferably, the mitt is formed from a fabric that is electrostatically charged or can acquire a triboelectric charge upon rubbing a surface, or from a fabric that is rendered tacky by the application of a tackifying agent.
By the design of these mitts, it is possible for the user to wear the mitt in such a way that the thumb is situated in one thumb compartment, and the little or fourth finger is situated in the other thumb compartment. The middle three fingers of the hand are then situated in the main compartment of the mitt. This arrangement is beneficial because it provides greater comfort and control of the mitt by eliminating the flap of fabric resulting from an empty thumb compartment when the fourth finger is placed in the main compartment of the mitt. Also, this arrangement provides better dexterity when dusting three-dimensional objects.

- DESCRIPTION OF THE PREFERRED EMBODIMENTS
Throughout the figures, like or similar reference numerals have been used for like or corresponding parts.
For illustrative purposes, the preferred embodiments of a mitt for cleaning and a method of forming a mitt for cleaning according to the present invention are described in connection with FIGS. 1 through 3.
Throughout this application, the digits of the hand will be referred to as follows: the thumb is considered separately from the four fingers, and the four fingers are numbered from one to four, in order from the index finger to the little finger. Therefore, the little finger is also referred to as the fourth finger herein.
Referring to FIG. 1, the dusting and cleaning mitt 1 of this embodiment of the present invention is formed from, for example, two pieces of a material suitable for use in cleaning household surfaces such as wood, linoleum, tile, and other hard surfaces. Of course, the invention is not limited to the use of two pieces of material. Preferably, the material is able to attract and retain common household dirt, such as dust, hair, dander, etc. The material should also leave behind very little lint on the surface to be cleaned.
According to the preferred embodiment of the present invention, the material used to form the dusting mitt is an electrostatically-charged fabric, or a fabric that is capable of acquiring a triboelectric charge. The fabric may be woven or non-woven. The material may be a natural or synthetic fabric, or a paper product, provided that it has been imparted with an electrostatic charge that causes the material to attract dirt, or is capable of acquiring such a charge. An especially preferred material is described in U.S. Pat. No. 5,525,397, which is incorporated herein by reference in its entirety.
According to an additional embodiment of the present invention, the material used to form the dusting mitt is a material that is treated with a tackifying agent. The material may be a woven or non-woven natural or synthetic fabric, or a paper product. The tackifying agent according to the present invention may be any substance that can be applied as a liquid to cause the surface of the material to render its surface sticky. Non-limiting examples of tackifying agents according to the present invention may include various oils (including synthetic, paraffinic, and silicone oils), silicone fluids, waxes (applied as liquids or emulsions), and/or surfactants, with preferred substances having a solid or paste-like consistency at room temperature, or substances that show only minimal transfer to the surface to be cleaned. The present invention is also not limited by the method of applying the tackifying agent to the material.
According to the preferred embodiment, the two pieces of fabric are cut in a shape that is symmetrical about a central axis (not shown) of the mitt 1, which runs from the top of finger area 30 to an opening 10 for the hand. The symmetrical shape is not a requirement for practicing our invention, but it simplifies forming the mitt and we have found is more appealing to the consumer. According to our embodiment, the pieces of material are in the shape of a mitten having a thumb compartment 40 on each side of the central axis. As will be demonstrated with respect to FIGS. 2 and 3, it is possible for the pieces to have a variety of other shapes, as long as an area 30 for the fingers and two compartments 40 for a thumb are provided.
The mitt 1 is formed by placing the two pieces of material together, and bonding them together (shown schematically by reference numeral 50) to produce the opening 10 for a hand, an area 20 for the palm of the hand, an area 30 for the fingers, and a compartment 40 for the thumb on either side of the central axis of the mitt 1. In forming the mitt 1, it is not critical whether the fabric is cut into the desired shape before or after the bonding step. It is also possible that the bonding and cutting steps can be carried out simultaneously.
The bonding 50 is preferably approximately in the shape of a hand having a thumb compartment 40 on each side of the central axis. The bonding 50 is performed, for example, by heat-sealing the two pieces of material together (according to the preferred embodiment), but it may also be done by ultrasonic welding, gluing, or sewing the two layers of material together, or by any other process that results in the two pieces of fabric becoming attached together. The bonding 50 may be in any design that roughly approximates the shape of a mitten having two thumb compartments 40.
The drawings show the bonding 50 being recessed from the edges of the mitt 1. This, however, is not limiting. In fact, where appropriate, the bonding may be provided at the edges along selected portions of the perimeter of the mitt, if desired. Also, where provided, the bonding may be continuous, or it may be discontinuous as long as the pieces of material are appropriately secured together. This is true for each of the embodiments.
By forming two compartments 40 for the thumb in the mitt 1, the mitt 1 can be used on either hand, and both of the surfaces of the mitt 1 can be used to collect and trap dust and dirt. This design is beneficial because it allows the consumer to use the mitt 1 on his or her dominant hand by inserting that hand into the mitt 1 and inserting a thumb into one of the two compartments 40 for the thumb, and optionally inserting the little or fourth finger into the opposite compartment 40. This design also makes it possible for the consumer to use both cleaning surfaces of the mitt 1 simply by rotating the mitt 1 one hundred eighty degrees with respect to the center line of the mitt 1, which runs from the area 30 for the fingers to the opening 10 for inserting the hand. The consumer then re-inserts the dominant hand into the mitt 1, and places the thumb into the second of the two compartments 40 for the thumb, and then continues cleaning.
The area 30 for the fingers is kept open according to the preferred embodiment. This allows the consumer a greater degree of freedom in using the mitt 1 to clean irregularly shaped surfaces. However, it is also possible to provide separate areas for each finger by bonding the material together to form, for example, two to four individual finger areas.
Turning to FIG. 2, the mitt 2 is formed from, for example, two pieces of material roughly shaped like a mitten with two compartments 40 for a thumb, in which the sections 60 between the thumb compartments 40 and the area 30 for the fingers are connected. The opening 10 for the hand, and the area 20 for the palm, the area 30 for the fingers, and the compartments 40 for the thumb are formed by bonding the material together as shown by reference numeral 50. The bonding is preferably performed to form the mitt 2 into the shape of a mitten having a compartment 40 for a thumb on either side of the central axis of the mitt 2, with additional bonding 50 connecting the areas 60 between the compartments 40 for a thumb and finger area 30.
This shape of the mitt 2 in this embodiment is beneficial in that it is easier to mass produce due to its simple shape, and results in less waste of fabric, which is otherwise caused by removing the areas 60 between the compartments 40 for a thumb and finger area 30.
As best seen in FIG. 3, the mitt 3 may be produced in an even more simple and cost-effective manner by utilizing a similar shape as the mitt 2 shown in FIG. 2, while using less bonding 50 to form the different areas of the mitt 3. In this embodiment, the outside edges of the material are bonded together, leaving an opening 10 for a hand to be inserted. Then, a compartment 40 for a thumb is formed on either side of a finger area 30 by bonding 50. This embodiment allows more flexibility in the overall shape of the mitt 3, and permits the mitt 3 to be designed so as to minimize the amount of fabric used.
The mitts according to our invention are preferably sized so as to accommodate the hand of an average adult. The mitts may also be provided in additional sizes to accommodate smaller or larger hands, if desired.
The dusting and cleaning mitt according to the present invention is primarily intended for use on dry, hard surfaces. Use with any kind of polish or liquid is not recommended as the product may pass through the fabric and come into contact with the user's hand. However, it is envisaged that the mitts could be constructed with an inner, impervious lining and such a concept is within the scope of the present invention. The lined mitts could then be used in conjunction with products such as furniture polishes, glass cleaners, and similar products.
In addition to the electrostatic or triboelectric properties of the mitt, another mechanism for removing larger particles of dirt using the mitt of the present invention involves grasping the dirt in the hand using the mitt, and then inverting the mitt while removing the mitt from the hand. This results in the larger particles of dirt becoming trapped inside the mitt, which may then be discarded. This allows the dirt to be removed without using additional apparatus such as a dust pan, and prevents the dirt from touching the hand of the consumer.
In their commercial form, the mitts of the present invention are intended to be disposable, and are provided in packs containing several mitts. The mitts are flat, allowing them to be stacked efficiently within the packaging. However, it is also possible to practice the present invention while producing a reusable, washable mitt if a durable electrostatically-charged material is used.
- INDUSTRIAL APPLICABILITY
The embodiments discussed above are representative of embodiments of the present invention and are provided for illustrative purposes only. They are not intended to limit the scope of the present invention. Although components, materials, configurations, and means of connecting various parts have been shown and described, such are not limiting. Modifications and variations are contemplated within the scope of the present invention, which is intended to be limited only by the scope of the accompanying claims.
The mitts of our invention are suited for use in cleaning surfaces, and are particularly useful in dusting. The two thumb compartments allow both sides of the mitt to be used during cleaning, and also allow the mitt to be used on either hand. The electrostatically-charged fabric used to form the mitt allows for more efficient removal of dust and dirt from surfaces. The method of forming the mitt according to our invention is a useful way to produce mitts for dusting and cleaning.
